I remember that, too, and I know what you mean. I remember the same thing when the ports of Pole Position II in Namco Museum had the Dentyne billboards taken out and replaced with generic Pac-Man and Galaga billboards. The different versions of Tapper I've seen had interesting product placements. The original version of Tapper was licensed by Budweiser, but some of the home versions, including the PC version and the Atari 8-bit version which was actually ported by Sega, replaced Budweiser with Mountain Dew.
That said, I'm generally not in favor of in-game advertising. I don't want to see Link shopping for bows and fishing rods at Cabela's outlets or staying at Best Western motels in Hyrule, and I'm not interested in seeing Mario in Dickies overalls and Justin workboots.
